To otll it may concern.

Be it known that I, LOUIS MAIGHE, a citizen.

5 of France,'resid ing at 368. Rue-"St. Honor, 1 Paris, France, have invented a certain new 55 and useful Improved Process '-for.the'Purifi-. cation of Spirits, of which the following is a specification. o I This invention has for its object the removal from spirit of the fusel-oil and other [-0 substances which give objectionable flavor I and odor-to the spirit For this purpose the 1 spirit to be purified is largely diluted with I water (it maybe up to five. times its volume) and subjected to distillation at a low temper- .13 ature, such as 25 centigrade, under avacuuin as complete as can convenicntly'be obtained. Under these conditions most of the impurij ties are distilled ofi, leaving the dilute spirit j comparatively pure. By further distillation and subjected to the distillationat low temperature and pressure, by which the impure ingredients are driven 0E, leaving pure dilute spirit. The operatiqn may be repeated sev-' .eral times till almost allthe spirit is recovered, leaving the impure ingredients by themselves. v

'Having thus described the nature of thisinvention and the best means I know of carrying thesame into practical effect, I claim- The process herein described of purifying spirit, consisting in diluting crude spirit with several times its volume of water, distilling at a low temperature in vacuo, thereby eliminating impurities, and finally concentrating the dilute spirit by distillation in the usual manner. I

In testimony whereof I have .signed my name to this specification, in the presence of 20 in the usual way the spirit thus purified can 1 be restored to any desired strength. As by the first distillation some spirit passes off with the impurities, the condensed liquid thus obtained-(it may be from several of the pri- 2 5 mary di'stillations) is again diluted with watertwo subscribing witnesses, this 8th day of 5 April, A.
